Globally, the United States is exceptional in that its census asks three separate questions: one about race, one about ethnicity, and one about ancestry. True False

True

Explanation:

From 1790 to 1950, census takers determined the race of the Americans they counted, sometimes taking into account how individuals were perceived in their community or using rules based on their share of “black blood.” Americans who were of multiracial ancestry were either counted in a single race or classified into categories that mainly consisted of gradations of black and white, such as mulattoes, who were tabulated with the non-white population. Beginning in 1960, Americans could choose their own race. Since 2000, they have had the option to identify with more than one.
